Liven up the performance or your set of keys with this Genuine TEIN Keychain that mimics the TEIN Coilover.

This is an actual metal, green and gold colored mini coilover which includes a sliding shock, a metal spring, and threaded pre load and locking rings so you can actually set the pre load on the spring and lock it in place with the included pair of Tein engraved ring tools.

This is a real functioning Coilover Keycain. It smoothly compresses and because you can adjust the pre load you can make it easy to start compressing and as you continue to compress it the spring continues to require more force to compress. Or adjust a lot of pre load and it will require a higher level of force to compress right from the start.
